Detailed Description
The application provides an elastic assembly applied to a connecting device of a flywheel assembly, aiming at the problem that the reliability of the flywheel assembly in the rotation process is not enough in the prior art. The elastic assembly comprises a buffering elastic sheet which is sleeved on the connecting device together with the elastic sheet and the gasket through a central round hole of the buffering elastic sheet. In the rotation process of the shaft system, stress is always transmitted from two sides to the inner transmission path for any part, so that the buffering elastic sheet in the embodiment of the application can effectively block the transmission path of partial stress, the stress intensity concentrated on the arc-shaped hole of the elastic sheet is reduced, the elastic sheet is prevented from being broken due to stress concentration, the reliability of the elastic assembly is obviously improved, and meanwhile, the reliability of the flywheel assembly where the elastic assembly is located is also improved.
In order to better understand the technical solutions of the present application, the following detailed descriptions of the technical solutions of the present application are provided with the accompanying drawings and the specific embodiments, and it should be understood that the specific features of the embodiments and the examples of the present application are detailed descriptions of the technical solutions of the present application, and are not limitations of the technical solutions of the present application, and the technical features of the embodiments and the examples of the present application may be combined with each other without conflict.
Generally, a flywheel assembly is an important device which is located between an energy output shaft and an energy input shaft, is used for storing energy and inertia outside a power stroke of an engine, and drives the energy input shaft to rotate through the energy output shaft. The energy output shaft may be a crankshaft and the energy input shaft may be a motor shaft. In the rotation process of the flywheel assembly, torsional vibration causes stress to be transmitted on a crankshaft, the flywheel assembly and a motor shaft, particularly on a connecting device in the flywheel assembly. The crankshaft is one of the most important components in an engine. When the crankshaft works, the crankshaft simultaneously bears the action force of gas in the cylinder, the inertia force of the reciprocating motion mass and the rotating motion mass and the action of torque at the power output end. The periodic excitation load and the guide shaft system are subjected to torsional vibration, so that alternating bending stress and torsional stress are generated on various parts of an engine crank and the like, and the phenomena of uneven stress distribution, stress concentration and the like can be generated on the crank shaft at the positions of an axial variable cross section, a transition fillet, a crank arm and the like. The torsional vibration (i.e. torsional vibration of the shafting) refers to the situation that the main machine transmits power to the energy receiving device through the shafting, so that the torsional angles among the shaft sections are unequal, and the shaft sections swing back and forth. That is, the shaft with certain rigidity (such as crankshaft and motor shaft) will always avoid torsional vibration during the rotation of the shaft system. However, the torsional vibrations and stresses have an adverse effect on components such as the flywheel assembly on the crankshaft: as the flywheel assembly is used, the stress concentration part is easy to break, so that the reliability of the flywheel assembly is reduced, and the service life of a part (such as a diesel engine) where the flywheel assembly is located is even reduced.
The application provides an elastic assembly applied to a flywheel assembly connecting device. Fig. 1 is a cross-sectional view of an elastic assembly according to an embodiment of the present disclosure. As shown in fig. 1, the elastic assembly 10 includes a first pad 11, a second pad 12, a buffering elastic sheet 13, and an elastic sheet 14. Wherein, the number of the elastic pieces 14 may be more than 1, a plurality of the elastic pieces 14 may be overlapped, and the buffering elastic piece 13 and the elastic piece 14 are commonly provided between the first pad 11 and the second pad 12.
Fig. 2 is a schematic structural diagram of the buffering elastic sheet 13 according to an embodiment of the present application. As shown in fig. 2, the buffer elastic sheet 13 is provided with a central circular hole 131 and first circular holes 132 circumferentially distributed along the central circular hole 131. The first circular hole 132 is disposed to effectively reduce the moment of inertia of the elastic buffer piece 13 and reduce the stress generated by the elastic buffer piece 13. The central circular hole 131 is used to allow the buffering elastic piece 13 to be sleeved on the connecting device 15. Fig. 3 is a schematic structural view of the elastic sheet 14. Referring to fig. 2 and 3, the first circular hole 132 of the buffering elastic sheet 13 is disposed opposite to the second circular hole 142 of the elastic sheet 14, and the arc-shaped holes 141 are distributed on the elastic sheet 14, and the arrangement of the arc-shaped holes 141 can reduce the rotational inertia of the elastic sheet 14 and the elastic assembly 10 when the flywheel rotates, and provide axial compensation, thereby preventing the elastic assembly 10 from elastic displacement. It can be seen that the arcuate aperture 141 in the resilient aperture 14 ensures that the resilient assembly 10 absorbs resilient displacement so that the resilient assembly 10 can be secured to the attachment means 15. The connecting means 15 may be a bolt. At the same time, during the rotation of the flywheel assembly, the elastic assembly 10 receives stress, which causes a problem of stress concentration.
Stress concentration refers to the phenomenon that the stress in a local range is remarkably increased due to sudden change of the geometric shape and the external dimension of a stress piece. When a material is stressed, the phenomenon that the stress on the surface and the internal defects of the material is far larger than the average stress is called stress concentration phenomenon, and is called stress concentration for short. For the spring assembly 10 of the present embodiment, stress concentrations occur primarily at the edges of the arcuate apertures 141 of the spring plate 14. Therefore, in the embodiment of the present application, the buffering elastic sheet 13 is disposed in the elastic assembly 10, so that the strength of the stress transmitted to the elastic sheet 14 can be effectively reduced. That is, in the embodiment of the present invention, even though the stress is still transmitted to the elastic sheet 14 and the stress concentration phenomenon occurs on the arc-shaped hole 141, the edge of the arc-shaped hole 141 is not broken again because the stress intensity is reduced, so that the reliability of the elastic assembly 10 is effectively improved.
In one embodiment of the present application, the buffering elastic pieces 13 may be respectively disposed between the first pad 11 and the elastic piece 14, and between the second pad 12 and the elastic piece 14, such that the elastic assemblies 10 are arranged in the order as shown in fig. 1: the first pad 11 and the second pad 12 are located at two sides of the elastic assembly 10, and then are the buffering elastic pieces 13, and the elastic pieces 14 are located between the buffering elastic pieces 13, so that the stress received by all the elastic pieces 14 is reduced in strength through the buffering elastic pieces 13, and the problem of fracture caused by the stress concentrated in the arc-shaped hole 141 of the elastic piece 14 can be effectively avoided.
In an embodiment of the present application, the thickness of the buffering elastic sheet 13 may be set to be 2mm, so as to achieve the effect of improving the protection effect of the buffering elastic sheet 13 on the elastic sheet 14. The material of the elastic piece 14 and the buffer elastic piece 13 can be 65 manganese or 70 spring steel.
Based on the elastic assembly 10, the application also provides a flywheel assembly. FIG. 4 is a cross-sectional view of a flywheel assembly provided in an embodiment of the present application. As shown in fig. 4, the flywheel assembly 40 is disposed on the crankshaft 43, and includes a wheel body 41 and a connecting plate 42. Wherein, the connecting disc 42 is used for connecting the outer flywheel 413 and the motor shaft. The wheel body 41 comprises an inner flywheel 411 and an outer flywheel 413, the inner flywheel 411 and the outer flywheel 413 are connected through a bolt 15, and the elastic assembly 10 is arranged at the connection position of the bolt 15. In the elastic assembly 10, the thickness of the buffering elastic sheet 13 may be set to be not less than the thickness of the elastic sheet 14, so as to ensure that the buffering elastic sheet 13 can effectively protect the elastic sheet 14, and avoid the stress from concentrating on the arc-shaped hole 141 of the elastic sheet 14, which results in the breakage of the elastic assembly 10.
By arranging the elastic assembly 10 at the bolt connection position of the wheel body 41, the influence of stress on the structure can be remarkably reduced in the rotation process of the flywheel assembly 40, the requirements on rigidity and elasticity in use can be met by the flywheel assembly 40, fatigue is avoided due to the stress, and the risk of shaft breakage can be remarkably reduced.
In one embodiment of the present application, a first stop 415 and a second stop 414 are respectively disposed on the outer flywheel 413, and a third stop 412 is disposed on the inner flywheel 411. Wherein, the first spigot 415 is positioned on the surface of the outer flywheel 413 on the side opposite to the connecting disc 42 and is used for radially positioning the connecting disc 42. The second seam allowance 414 is located on the surface of the outer flywheel 413 on the side opposite to the inner flywheel 411, and the third seam allowance 412 is located on the surface of the inner flywheel 411 on the side opposite to the outer flywheel 413. The second and third stops 414, 412 may collectively be used to radially position the elastomeric assembly 10. The first spigot 415, the second spigot 414 and the third spigot 412 are arranged to ensure that the parts in the flywheel assembly 40 are tightly connected, so as to achieve the purpose of improving the power output of the flywheel assembly 40.
Fig. 5 is a schematic structural diagram of a connection pad provided in an embodiment of the present application. As shown in fig. 5, a plurality of third round holes 421 are provided on the connection disc 42. The third circular hole 421 can reduce the weight of the connecting disc 42 to reduce the connecting disc 42 and the moment of inertia of the flywheel assembly 40 where the connecting disc 42 is located, so that the reliability of the connection between the wheel body 41 and the connecting disc 42 in the flywheel assembly 40 can be further improved, and the stress on the connecting shaft is reduced, thereby effectively improving the reliability of the flywheel assembly 40.
In one embodiment of the present application, the area of the pressing contact surface 422 of the outer flywheel 413 and the connecting disc 42 is not less than 7.9 × 10 4 Square millimeter. That is, the outer circumference of the contact surface 422 provided on the end surface of the outer flywheel 413 is pressed. The embodiment of the application can ensure that larger torque is transmitted under the condition of the same axial force by increasing the area of the pressing contact surface 422. Therefore, the arrangement of the pressing contact surface 422 in the above-mentioned application embodiment can effectively improve the torque transmission capability of the flywheel assembly 40.
Further, in order to verify the reliability of the flywheel assembly 40, the present embodiment respectively performs simulation on the flywheel assembly 40 and a flywheel assembly without the damping elastic piece 13, please refer to table 1.
TABLE 1
| Flywheel assembly serial number | Axial stiffness | Fatigue safety factor |
| Flywheel assembly A | 1.8KN/mm | 1.339 |
| Flywheel assembly B | 1.9KN/mm | 1.631 |
| Flywheel assembly C | 2.0KN/mm | 1.341 |
The flywheel assembly B is the flywheel assembly 40 shown in fig. 4. In table 1, the flywheel assembly a, the flywheel assembly B, and the flywheel assembly C are different only in the elastic assembly. Specifically, the elastic assembly of the flywheel assembly a includes 10 elastic pieces each having a thickness of 1 mm. The elastic assembly of flywheel assembly B includes 8 flexure strips and 2 buffering flexure strips, sets up 1 buffering flexure strip respectively in the both sides of these 8 flexure strips, and the thickness of buffering flexure strip and flexure strip is 1 millimeter. The elastic assembly of the flywheel assembly C comprises 8 elastic pieces, the thickness of the middle 6 elastic pieces is 1 mm, and the thickness of the elastic pieces on the two sides is 2 mm. As can be seen, the total thickness of the resilient assembly of flywheel assembly A, B, C is 10 millimeters.
The fatigue safety factor refers to the degree to which fatigue fracture occurs when the member is subjected to the same force, and the effect of that degree on the overall safety of the member, and thus the fatigue safety factor can be used to indicate the reliability of the flywheel assembly. Therefore, their reliability is, in order from high to low: flywheel assembly B, flywheel assembly C, flywheel assembly A. It can be seen that the flywheel assembly provided in the embodiment of the present application (i.e., flywheel assembly B) has the highest reliability. The reason why the reliability of the flywheel assembly a and the flywheel assembly C is not very different is that although the thickness of the elastic sheet at the outermost side in the flywheel assembly C is 2 times that of the elastic sheet in the flywheel assembly a, the thickness can reduce the risk of fracture caused by stress concentration of the two elastic sheets at the outermost side of the elastic assembly of the flywheel assembly a, the increase of the thickness causes increase of axial rigidity, which is not beneficial to connection between an engine and a motor, and therefore, the increase of the thickness of the elastic assembly cannot significantly improve the reliability of the elastic assembly and the flywheel assembly. That is to say, the flywheel assembly provided in the embodiment of the present application, to the improvement of reliability, not only can reduce the risk of fatigue fracture due to stress concentration and other reasons in the flywheel assembly, but also can ensure the safe connection between the engine and the motor.
To sum up, this application embodiment provides an elasticity assembly, is applied to the connecting device of flywheel assembly on, this elasticity assembly blocks the stress that comes from the outside transmission through buffering the flexure strip for fracture does not appear in the arc hole on the flexure strip because of stress concentration, thereby effectively promotes the reliability of elasticity assembly. Further, the embodiment of the present application provides a flywheel assembly, in the flywheel assembly, the above elastic assembly is disposed at a bolt connection position of the inner flywheel and the outer flywheel, so that reliability of the flywheel assembly is also improved. Meanwhile, the purpose of reducing weight of the connecting disc is achieved by arranging the third round hole in the connecting disc, so that the rotational inertia of the connecting disc and the flywheel assembly is reduced, the risk of shaft breakage is effectively reduced, and the reliability of the flywheel assembly is improved.
